I have no problem with the product, which I have used many times before, but I have a complaint on the way I received it. I waited 2 weeks for delivery & when it finally arrived it came from Hong Kong & needed a signature. As I was not at home for the first attempt on a Saturday, I did not get it until the following week when I had to pick it up at the local Post Office. It was inconvenient to say the least & seemed way too complicated for a product that is sold at many local stores. I used AMAZON because you have always had very quick delivery so this was a surprise & disappointment. I was also never told that there would be a delay of any kind. I have always had very good service through AMAZON in the past.
